3. Concise Utils

Concise Utils is one of the official add-ons for Concise CSS. It provides helper classes that you can use in your markup for fast prototyping or context-dependent styles.

Helper classes are prefixed with an underscore (_) to distinguish them from components or elements.

3.1 Borders

There are several classes available to delete or add borders to elements. Those classes begin with a b, the initial letter of the side where the class works (optional) and the size of the border from 0 to 4.

Classes that work on all the sides are composed only of the letter b and the width, for example, _b1.

3.2 Colors

All the colors in the color palette are available as classes to be used directly within your HTML.

The classes for text colors are prefixed with _c- and _bg- for backrounds.

The color follows the same schema in the $colors map. For example, you can use the color obtained with getColor(base, primary) in HTML as _c-base-primary for text or _bg-base-primary for backgrounds.

3.3 Columns

Is possible to split the content into several columns, up to 12 by default, using the column utilities.

Those classes use the Multicolumn layout, so they are distinct from the grid included in the core of Concise CSS.

Also, there is a class to build masonry-type layouts with pure CSS quickly.

Columns

<div class="_cols-1">…</div>
<div class="_cols-2">…</div>
…
<div class="_cols-11">…</div>
<div class="_cols-12">…</div>

Gap between columns

You can set the space between the columns, by default it will have the value of the $gutter variable.

<div class="_col-gap">…</div>

Masonry layout

<div class="_masonry">…</div>

3.4 Hide/Show

You can hide or show elements depending on certain key points, like the device size, resolution, or media (printing or screen).

Show elements

<!-- Show only on extra small devices -->
<div class="_show-xs">…</div>

<!-- Show only on small devices -->
<div class="_show-s">…</div>

<!-- Show only on medium devices -->
<div class="_show-m">…</div>

<!-- Show only on large devices -->
<div class="_show-l">…</div>

<!-- Show only on extra large devices -->
<div class="_show-xl">…</div>

<!-- Show only on print -->
<div class="_show-print">…</div>

<!-- Show only on high density (retina) devices -->
<div class="_show-hd">…</div>

Hide elements

<!-- Hide only on extra small devices -->
<div class="_hide-xs">…</div>

<!-- Hide only on small devices -->
<div class="_hide-s">…</div>

<!-- Hide only on medium devices -->
<div class="_hide-m">…</div>

<!-- Hide only on large devices -->
<div class="_hide-l">…</div>

<!-- Hide only on extra large devices -->
<div class="_hide-xl">…</div>

<!-- Hide only on print -->
<div class="_hide-print">…</div>

<!-- Hide only on high density (retina) devices -->
<div class="_hide-hd">…</div>

3.5 Display

The display properties are also exposed via HTML classes so you can use them in your markup quickly.

<!-- Equivalent to display: inline-block -->
<div class="_inline-block">…</div>

<!-- Equivalent to display: block -->
<div class="_block">…</div>

<!-- Equivalent to display: inline -->
<div class="_inline">…</div>

<!-- Equivalent to display: flex -->
<div class="_flex">…</div>

3.6 Margins

As with the borders, you have predefined classes to reset or add margins. They will use the value in the spacing variables defined in the settings file.

These variables can be especially useful to keep your CSS clean, by adding margins in your markup depending of the context without having to create extra styles, or a component/element variant.

Reset margins

<!-- Reset all margins -->
<div class="_m0">…</div>

<!-- Reset top margin -->
<div class="_mt0">…</div>

<!-- Reset right margin -->
<div class="_mr0">…</div>

<!-- Equivalent to position: absolute -->
<div class="_abs">…</div>

<!-- Equivalent to position: relative -->
<div class="_rel">…</div>

<!-- Equivalent to position: static -->
<div class="_sta">…</div>

3.9 Type Scale

The first ten sizes in the primary type scale are available to use in HTML; those are built using the typeScale() function and are updated depending on your settings.

<!-- Equivalent to typeScale(1) -->
<div class="_ts1">…</div>

<!-- Equivalent to typeScale(2) -->
<div class="_ts2">…</div>
